iMPRovEo GOVERNOR-VALva Specification forming part of Letters No. 34,523, dated February 25,1313?.

To all whom it may concern:

Be it known that we, JOSEPH REIOHMANN and HEINRICH KRIETE, of Chicago, in the county of Cook, in the State-of Illinois, have invented a new and Improved Mode of Constructing Steam-Governors; and wedo hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. e The'nature of ourinvention consists,first,of anarrangement permitting steam from theboil er and-'steam from the cylinder of the engine to act against each other upon a piston or its equivalent. Any eect orditference arising between the said pressures will cause the regu-v lation of the quantity of steam to be admitted to thecylinder of the engine to operate her with equal speed. Second, of an arrangement connterbalancing the piston or its equivalent upon which the boiler-steam and that of the cylinder of the engine act against each other. To enable others'skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

Figure 1 is avertical section of the steamgovernor. Fig. 2 represents a side elevation of the steanrgovernonland a section through cylinder J. Fig. 3 is a plan Aof the steam-- governor. Fig.l 4 represents a horizontal section of the rod I, at Q. (See Fig. l.) Fig. 5 is a horizontal section of the cylinder c and of the rod I at L. (See Fig. 1.)',Fig- 6 is a horiiontal section of thelcylinder F and of the rod I at A. (See Figl 1.)

We constructeur governor of the following parts: tirst,ofvcylinder`H,with the steam-ports :c az, which is fastened into the globe-chamber It R by means of screw h h, and lap m m; second, of cylinder F, which is fastened above and in line with cylinder H, by means of four bolts, to the flanges U ofthe globe-ease R R; third, of piston I?, (fitting cylinder F"steam-tigl1t, but allowing the sameto fall by its own weight,)

edividing cylinder F into two independent chambers, e and e; fourth, of the pipe K, forming a connection between the cylinder of the engine and the cylinder for the purpose of carrying the steam of the cylinder of the engine into cylinder F, space e', and under piston, 1?; fifth, of cylinder c c,;placed on the top of cylinder 'F and in line with it. It is fastened, by means of `four bolts, t the top flange of cylinder F; sixth, of a piece-pipe, .e e, which is screwed intothe center of the Lbottom of the cylinder c c, fitting rod, I steamtight. The lower part of rod `Lent-ending into the cylinder H, has the object to communicate any change in the position of the piston I di'- rectly to the governor-Valve N, N fitting`cyl-- l .inder H steam-tightf) The upper part of rod I, extending through cylinder F into cylinder c, has the object to cut off or to admit the proper quantity of boiler-steam by means of the tapering steam-.grooves w agent into the rod I, to act upon piston?, chamber e. Pipe t, forming a connection between the boiler and cylinder c, cylinder c; seventh, of'nut o o, fastened to the top end of rod L-'preventing the same from dropping beyond the position shown 'in 1. As rod I is also in connectionwith governorvalve N, said shown position of rod I is such when the engine' is n ot operated and the position of the governor-valve is such as to give steam-port (see Fig. 1) to start the engine with it,and also to lift piston P as muchas to throw valve N into such position as tov allow the steam to pass under it, instead of over it, as it is in the moment only when the steam of the boiler is given to the engine J of the cylinder b, which forms the coverof the cylinder c,and allows-the rod I to play freely in it. A small screw, a, seen at the top of cylinder I), allows the oiling of rod I with its connections.

The arrangement for the counterbalancing of piston l? with its connection consists of the parts as follows: first, of cylinder J, in connection with cylinderF by means of the steampassage d d; second, of cylinder-head B, con*- taining a'half-circular tapering steam-groove, y y, which is in connection with a pipe, 'Wg third, of a circular plate-valve, M, with the opening U. Valve M is held or guided by the valve-stem p p, which turns at one end in the cylinder-head B, at the other in a guide opposite to the-.cylinder-head I5; fourth, ot the lever-arm a and connectingrod m', the vobject of which is to communicate motion 'to valve-stem p p,and conscquentlythe valve-M. a

This arrangement described produces the balancing or cou'nt'crbalancing of the piston I and connections by exhausting a certain porti'on of boiler-steam acting upon piston Pin chamber c.

The operation of our governoris the follow-l carries the boiler-steam into e 'il Y34,523
